Local Haznmt Spills <br />Site Specific <br />Documented regulatory agency sites located within the ASTM prescribed mini►num search distance <br />will be identified and plotted on a composite site map. <br />Physical Setting Sources <br />USGS Topographic Map(s) will be reviewed to determine site topography and surface drainage <br />patterns of the site and the surrounding area. Current and past structures, roads, well installations, <br />and other improvements will be evaluated, as well as other pertinent physical features such as <br />streams or water bodies. Federal Emergency Management Agency floodplain map(s) will be <br />evaluated to determine if the subject property lies within a known floodplain. The appropriate Soil <br />Survey from the USDA Natural Resource Conservation Service will be reviewed to determine <br />the site's soil conditions and general surface geology of the area. General descriptions will be made <br />of the subsurface hydrogeology based on information from USGS Groundwater Maps or other <br />sources. <br />Historical Use Information <br />Historical Aerial Photograplis will be obtained from aerial photography firms having inventory of <br />the subject area.

This information will be obtained from a <br />Regional Oil and Gas Survey Map prepared by Tobin Research, Inc. <br />Task 2: Interviews and Agency Inquiries <br />owner/occupant Inquir <br />Inquiries will be made of person(s) who may have knowledge of current or historical conditions <br />associated with the subject property.
